Agreed. I've looked at this problem extensively and concur that
readline is the culprit; I don't think there's any solution on our end
besides filing a bug with the readline. I also agree with the
upthread suggestion that the best workaround today is to \e into a
non-readline based editor (vim qualifies). Having said that, at least
on linux/gnome, very long pastes can cause severe performance issues
as well. So for large pastes I go with psql -f.
